Chondrostoma cyri orientalis Bianco [P. G.] & Bănărescu [P. M.] 1982: 80; Type locality: Pulwar River near Persepolis, Iran. Holotype: IZA 8170. Paratypes: (85) ANSP 150985 (2), ISBB uncat. (10), IZA 7833 (orig. 75,? now 19), FMNH 94519 (2), NMC 82–365 (6), USNM 227934 (1).
Common name: Pr: Kapore poze dar-e Kor, En: Oriental nase, Kor nase.
Diagnosis: This species similar to C. esmaeili but distinguished by having arched mouth (vs. straight or slightly arched), shallowly forked caudal fin with rounded lobes (vs. forked caudal fin and pointed lobes, short snout length (17–21 vs. 25–33% SL), short head width (45–64 vs. 55–64% HL), and lower number of gill rakers (15–17 vs. 25–34).
Meristic characters: D: IV 7–8 (8), A: III 9–10 (9), P: 15–17, V: 8–9, GR: 25–34, LL: 49–57, TV: 42–45.
Distribution: Kor River basin ( Fig. 246).
Taxonomy: Elvira (1987) gave it full species rank.
Conservation: IUCN: Not Evaluated, PC: Critically Endangered B1ab(i,ii,iii,iv). In our exhaustive field work in the Kor River during the last 10 years, no individual of this species has been found. The only locality where some individuals of the species still may survive is the Drodzan Dam reservoir (not confirmed). To the best of our knowledge, only a few fixed samples of this species are available at the zoology museum of the university of Shiraz. Consequently, we classified the species as Critically Endangered, possibly Extinct (on a precautionary basis), and recommend more surveys.
